Himalay Putra begins by tracing a tender, forbidden romance between Suraj Vinod Khanna, a police inspector with a modest income, and Seema Hema Malini, the daughter of a wealthy businessman. Their love faces a rigid barrier of status, and Seema's father, Mr. Malhotra Amrish Puri, strongly objects to the match, casting a long shadow over their early happiness.
As pressure mounts, Seema’s doubts are fanned by the family’s objections, and she begins to see Suraj through the lens of distrust, suspecting that his affection is entangled with money rather than pure love. The situation deteriorates as misunderstanding takes root, threatening to tear the couple apart.
Seema becomes pregnant, and after her father's death, she retreats to the hills of the Himalayas, where she gives birth to Abhay. Abhay grows up with a skewed view of his father, hearing only his mother’s version of the past, and he becomes a devout follower of Lord Shiva. He even refers to his father as Himalay Putra, a name that ties him to the mountains and to a legacy he has yet to understand.
Love enters Abhay’s life when he falls for Esha Anjala Zaveri, the daughter of their neighbor Major Mathur Satish Shah. Yet romance is only part of Abhay’s life; his deeper mission is to discover his father and to right the sorrows that shadow his mother’s memory, a quest that drives his choices and fuels his resolve.
Fate aligns the paths of father and son when Abhay encounters Suraj again. Suraj has now risen to the rank of Assistant Commissioner of Police and is on the trail of a ruthless smugglers’ gang led by Rana Danny Denzongpa. In a pivotal moment, Suraj saves Abhay’s life, and a complex bond begins to form between the two men, built on respect and a shared history that neither fully acknowledges.
Abhay, eager to bring Suraj into his family circle, brings him home and introduces him to Seema. The reunion shocks both parents, who are stunned to see each other after two long decades, yet they choose not to reveal their prior relationship to Abhay, opting for silence to protect him from the truth for the moment.
But the weight of the past resurfaces as the smugglers’ activities create a situation in which Abhay learns that Suraj is his father. The revelation tests loyalties and loyalties, but it also sets the stage for a dramatic shedding of old misunderstandings. In the end, the family’s bonds are repaired, misunderstandings dissolve, and they move forward together with a sense of renewed hope and unity.
